The new Atom-based "micro-architecture," codenamed "Silvermont," will ship in 2013, adding a spanking new architecture on top of the new transistor structures, industry sources familiar with Intel's plans told CNET. This will be the first architectural change since Atom--widely used in small laptops today--was announced in 2008.
When coupled with the 3D transistors, Silvermont is expected to enable new levels of integration and performance and make major strides in power efficiency.

Atom is now on a fast track, according to the sources. Intel will accelerate the Atom processor roadmap at a pace faster than Moore's Law, which generally states that the number of a transistors that can be placed on a chip doubles roughly every two years. Atom SoCs are shipping now at 45-nanometer, moving to 32-nanometer in volume later this year, and then the Silvermont SoC's married with the new architecture will ship in 2013. This results in three process generations and one new architecture inside of three years, according to sources.
